Figures 15 and 16 illustrate apreferred form of notching. andv turning the' sealing strip at thecorners of the sash.

The present invention is illustrated in an improved sash constructionior conventional Windows. Figure 1 shows a Window sash assembly Wconsisting of a glass sheet or panel I, a sash frame 2 surrounding theedges' of panelV I, and gripping and sealing means 3 disposed betweenthe edges of panel I` and! thesash frame 2. My sash assembly may be usedin any type-of window construction, either and preferably as anindependently operated' and installed completesaslfi` or may be glazedinto or incorporated with existing sash framesor other xed or movableapertures or openings.

The details' of construction of the sash are shown in' Figuresv 2, 3,4,. and r4. The sasl-i, or

more specically the. sash frame 2 is comprised of a, top rail abottcmrail 5, and side` rails 6'- and l'. For convenience and clarity inexplain-- mg the details of construction of my` invention,

reference'v will presentlyI be made only to one rail', y namely top:rari 4- sho-wn in Figure 2, since the 3 y top, bottom and side rails aresubstantially identical in form and coact with the seal and glazing inthe same way. Rail 4 is preferably cut to proper length from suitablerigid material, l

such as aluminum, brass, steel or stainless steel, having a channelshaped cross section, and having an outer or base wall 8 and spacedparallel side walls 9 and I integral with and projecting inwardly fromthe base wall 8. The inner surfaces of walls 8, 9 and IB define an openrectangular recess in the rail which is adapted to receive the marginaland extreme edges of the glass or other panel I, In order to seal andretain panel I in rail 4, resilient gripping and sealing means 3comprising a channel-shaped rubber or rubber-like sealing member orstrip is disposed in recess |I between the edgesof panel I and the rail.

The sealing member or strip 3 preferably isA comprised of rubber orsimilar resilient material andmay be formed by extrusion through a die.The strip preferably is cut to a length substantially equal to theperiphery of panel I so as to form a continuous seal between the paneland sash frame. The strip is formed with'a web I3 and spaced inwardlyprojecting legs I4 and I5 preferably formed integrally with web I3. WebI3 has an inner surface I6 and an outer surface I'I, and legs I4 and I5have inner surfaces I8 and I9, respectively, and outer surfaces 20 and2|, respectively. The inner surfaces I6, I 8 and I9 of web I3 and legsI4 and I5, respectively, define a slot or groove 22 in the strip 3, seeFigure 4, into which the outer marginal and eX- treme edges of panel Iare adapted to fit closely when the strip and panel are joined. Thestrip 3 is formed so that in its relaxed dismounted state legs I4 and I5preferably tend to converge toward each other as shown in Figure 4. Inorder to fit the marginal edges of glass panel I into slot 22 of thestrip, legs I4 and I5 are sprung outwardly from each other and thustend, pro tanto, to grip the edge of the panel. When the panel edge ispositioned in the slot 22 legs I4 and I5 tend to converge toward eachother and inner surfaces I8 and I9 of the legs snugly engage themarginal sides of the panel whereby to retain the strip 3 on the edge ofthe panel as shown in Figure 3 at least initially and to aid in handlingand assembly-with the sash frame.

In order to create and maintain an air tight seal and a strongmechanical grip between the strip 3, the panel and sash and topositively and effectively bind the window panel and sash together, aplurality of ribs 23 and 24 are formed integrally with legs I4 and I5 ontheir outer surfaces 26 and 2| respectively. In an exemplary stripmeasuring about 1 2 wide by deep overall in the condition shown inFigure 3, these ribs may be relatively small in size being about le"long from root to tip and about els" mean thickness and are preferablyspaced on the surfaces 243 and 2| in the order of about 6 to 12 to aninch. Ribs 23 and 24 extend longitudinally of the strip and project fromthe respective legs I4 and I5 in an inclined direction away from the webI3, i, e., inclined to yield easily during entry of the strip into therecess of the rail and strongly resist removal of the strip from therail. 'I'his construction permits the ribs to be pressed and foldedinwardly toward or against the surfaces 20 and 2| of the strip underrelatively small manual pressure when the sash rail is forced over andupon the sealing member as to the position shown in Figure 2, althoughthe ribs when so folded or bent inwardly exert an outward resilientpressure back against the inner surfaces of the legs of the rail becauseof their resiliency. The overall width of strip 3 when mounted on thepanel edge, that is, the distance between tips of ribs 23 and 24 asshown in Figure 3, is about ie" in the exemplary form mentioned aboveand is about greater than the corresponding distance between innersurfaces of side walls 9 and I0 respectively of the rail, that is, thewidth of recess II. When strip 3 is telescopically fitted into recessIl, ribs 23 and 24 will engage side walls 9 and I respectively and willbe folded or displaced inwardly toward or against the outer surfaces and2| of legs I4 and I5 as the strip and panel are moved into the recessand at the same time will press outwardly against the inner side walls 9and I0 of rail 4 as Vshown in Figure 2.

When the strip 3 with panel I mounted therein is inserted into recess II, frictional resistance to sliding between the engaging surfaces of therail and the ribs is compensated by the inwardly yielding folding actionof ribs toward or against the outer surfaces 2B and 2| of the legs I4and I5, respectively. Thus, insertion of the strip into the recess ofrail 4 during assembly of the sash and glass panel is but lightlyresisted. However, once the glass panel, sealing strip and rail havebeen joined as shown in Figure 2, frictional forces opposing removal ofthe strip and panel from the rail become exceedingly high. The reasonfor this action is that intended movement of the panel in a directionaway from the rail and out of recess causes the ribs 23 and 24 to tendto unfold or expand outwardly and correspondingly increase the eiectivethickness of the rubber and multiply the frictional grip between thesealing and gripping member 3 and the rail and the panel. Thus, highfrictional resistance which increases with the force tending to removethe panel from the rail substantially prevents disassociation of thepanel, strip and rail and the window panel is securely and tightlylocked and sealed in the rails of the sash frame.

As previously mentioned, legs I4 and I5 of the strip 3 converge towardeach other when the strip is dismounted from the panel I. Thispreliminary engagement of the legs of the strip against the peripheralmargin of the window panel is increased when the strip and panel edgeare inserted into the recess of rail 4, and when the panel is sought tobe separated from the rail the compressive engagement and frictionalbond between all the parts is mightily increased as described above.When it is desired to remove the glass panel from the sash, as forexample, in

the event of window breakage, a small amount of kerosene or other lightpenetrating oil may be deposited on each side of .the glass panel at thejunction thereto kwith the strip 3. The oil penetrates between thesurfaces of the glass panel vand the inner surfaces I8 and I9 until thecoefficient of friction between the strip and panel is loosenedsuciently to permit the glass to be withdrawn from the strip. If thestrip 3 is composed of natural rubber the application of kerosene or thelike may be detrimental to the structure of the material; in which casethe rubber strip may be replaced with a new one before reassembling thesash frame and panel. Often a prompt wiping olf of the kerosene willpreserve the strip for repeated use. However, if the strip Vis composedof such material as synthetic rubber and the like, deteriorationfromkerosene is less likelyy and it is only necessary that the strip bewiped clean of the` oil in order to restore its coeiicient of frictionfor use again in the sash frame.

As shown in Figures 2, 3 and 4, I prefer to form the sealing strip 3with outer integral flanges 25 and 25 on the free endsl of legs ld andl5 respectively. These iianges project outwardly from the ends of thelegs and are adapted to overlay the inner portions of the ends of thelegs 9 and I0 of the rails and effect engagement therewith as the stripand/or strip and panel are inserted into the recess tI of the sashrails. Thus, flanges 25 and 26 act as yieldable stops to limit themovement of the strip into the recess of the rail and to locate thestrip in the sash. In addition, flanges 25 and 26 facilitate theweatherproofness of the seal and are preferably tapered at their outerends to merge with the curves of the ends of the legs to spill rain,wash water, etc., from the glass out over the exterior of the rails. Asalso shown in Figure 14 the free ends of the legs 9 and Hi are roundedat their inner and outer corners; the former facilitating smooth entryof the strip and panel into the recess II, wiping and folding or bendingthe ribs 23 and 'Ze without tending to shear or sever the same from thestrip during its entering movement into the recess, and the lattermerging in contour with the tapered ends of the iianges 25 and 2Sthrough a wide range of positions of the iianges according to the depthof entry of the strip into the recess, as suggested by the contrastingpositifns shown in the right and left parts of Figure 14.

Referring now more speciiically to Figures 2, 5 and 14 the facility withwhich my sash accommodates irregularities in the shape and contour ofthe panel I within fixe-d sash dimensions is suggested. In Figures 2 and5, the extreme outer edge 28 of the panel I is shown as having detailedirregularities departing from straightness as often occurs in thecutting of glass. Here the high parts have merely exed the web I3 of thestrip 3, see also the dotted lines in Figure 2, toward the base wall 8of the rail without substantially drawing or urging the legs I4 and I5of the strip inwardly beyond their normal position in the recess assuggested by the full overlap of the flanges 25 and 26 with respect tothe rounded ends of the legs 9 and I0. The low points of the irregularedge 23 need not necessarily touch the web I3 of the strip; theessential grip and seal between the strip and panel being made on themarginal edges of the panel between the surfaces It and I9 and theyieldability of the web I3 taken with its spacing from the base 8 of therail accommodating these irregularities in the edge 28 without bottomingthe strip or edge, thereby preserving the edge in the nrst instance andaccommodating relative thermal expansion and contraction between theparts in use.

Since it rarely happens that the panel I is cut truly square it willoften happen that the edge of the panel will extend more deeply into onerail or one part of a rail than another. As suggested in Figure 14 thestrip 3 accommodates this kind of irregularity without loss of grippingor sealing efficiency and without substantial change in finish orappearance. On the left side of Figure 14 the parts are shown in themean or normal relation similar to that of Figure 2 With the flangemaking full contact with the end of the leg of the rail but not beingsubstantially flexed thereby. Here the edge 23. is shown `justcontactingy the web I3'v and the web in turn is well spaced from thebase of the rail as by about 1A," where the other dimensions are asgiven above and the `panel is normally proportioned in respect to. the`rail.. The right side of Figure 14 shows how my invention accommodates.an oversize panel or a panel having an oversize dimension. Here thewhole strip enters the recess II more/deeply carrying the web and legsthereof deeper into the recess and drawing the inner portion of theflanges, as illustrated by the flange 26, partly into the recess. Theouter part of the flange with its tapered extremity still makes smoothtight contact with the rounded end of the leg of the rail and presentsthe same finished appearance and substantially the same contour or theso-called normal condition. Again the web of the strip is still spacedfrom the bottom of the recess with the advantages above mentioned, thesame being accomplished by making the recess enough deeper than thenormal depth of the strip, as measured from the flanges to the-exteriorof the web, to accommodate all reasonable errors in panel size and shapeand still have a space between the bottom of the recess and the bottomof the strip.

One exception to this latter teaching has occurred in my experience,namely, when the glazing or panelling is heavy as in a large multipleglazed sash the glazing and strip may tend to work down into the bottomrail under the iniluence of gravity and use of the window more than Idesire. Against such contingencies I have found it practicable andadvantageous to insert a pad or cushion in the bottom of the recess ofthe bottom rail of depth approximately equal to the normal space betweenthe webs 8 and I3 as shown at the left of Figure 14 so that the web I3of the strip and the glazing may have soft somewhat yielding supportdistributed between the high and low parts of the bottom edge of theglazing equally enough to resist cracking of the glass and cutting ofthe strip. I have found a soft wood pad practicable; the rubber Voi theweb I3 of the strip tending to cold-flow and distribute the load fromthe high parts to the low parts of the glazing satisfactorily.

There yet remains the accommodation of variations in thickness of thepanel in relation to the desired constant width of the recess II. Insingle glazed sash the variation is ordinarily small enough to becompensated for in the extent of the bending and flattening of the ribs23 and 24; their functions and effects not being deleteriously impairedin the range between substantial flexing on the one hand and completebending to bottom against the surfaces 29 and 2| on the other hand.Where greater accommodation is desired the inner surfaces I3 and I9 maybegrooved, serrated or corrugated as show-n at 59 in Figure 8 so thatthe attening of the ridges of the serrations will facilitate greatertolerance of variations in panel thickness.

Figures 6, 7 and 8 show a modification of my improved sash foraccommodating double glazing. Sash 3d is comprised of top rail SI,bottom rail 32, and side rails 33 and 3d, all of which rails aresubstantially similar in form and shape. Each of the rails 3i and 32 hasan outer wall 35 and side walls 36 and 3l projecting inwardly from wall35. The inner surfaces of these walls deiine vrectangular recesses 4I inrails, corresponding to the recess II except in size, which are adaptedto receive the edges of spaced parallel glass panels 43 and 44. In orderto seal; space "i and securely hold the panels 43 and 44 in the railrecesses and to space the panels from each other, a sealing member orstrip 45 of rubber or rubber-like material corresponding generally tothe strip 3 adapted to be inserted in the recesses of the rails isprovided. This sealing member preferably is a single strip designed toextend around the entire peripheries of panels 43 and 44. Although Iprefer to use a single sealing strip, it will be understood thatindividual strips cut to the length of each rail member, respectively,may be employed without departing from the spirit of my invention.

Sealing strip 45 consists of a web 41, inwardly extending side legs 48and 49, and an intermediate leg or dividing partition 59. Legs 48, 49and 59 are preferably formed integral with web 41. The intermediate leg50 is spaced from the side legs 42 and 49 thereby -dening slots 5I and52 between the side legs and leg 59 for receiving the extreme andmarginal edges of panels 43 and 44, respectively, which extendlongitudinally of the strip. When panels 43 and 44 are mounted in thestrip with their edges disposed in slots I and 52, respectively, asshown in Figure 7, intermediate leg 5! serves to separate the panels sothat a space 53 exists between them. It is well known that provision ofa space, commonly known as dead air space, between the panels of awindow assembly greatly increases the insulating characteristics of thewindow and reduces heat loss therethrough.

As described in connection with the sealing strip 3 shown in Figures 2,3 and 4, legs 48 and 49 of the strip 45 are provided with sets ofexternal integrally formed longitudinally extending ribs 54 and 55,respectively, which project outwardly from the legs and away from theweb 41 and perform the function of the ribs 23 and 24 of the strip 3.Flanges 56 and 51 are formed on the free ends of legs 48 and 49,respectively, which flanges cooperate with the rail into which thesealing strip is inserted to properly position the strip therein and toperform the other funce tions ascribed to the flanges 25 and 26. Thesurfaces on intermediate leg 50 adjacent the slots 5l and 52 arepreferably formed with a plurality of longitudinally extendingserrations 59 adapted to contact the inner surfaces of panels 43 and 44and which provide leg 5D with sufficient resilient effectivecompressibility to help accommodate for variations in thickness of thepanels and relative thermal expansion and contraction of the panels andthe sash.

As shown in Figure 8, strip 45 is formed so that in its relaxed statewhen dismounted from the edges of the window panels, side legs 48 and 49converge or tend to converge inwardly toward leg 5G. This constructionaffords a gripping action tendency of the strip on the edges of thepanels whereby to retain the panels in the slots 5I and 52 in the mannerdescribed previously and/or to hold the strip on the edges of l thepanels preliminary to assembly in the sash rails.

In the assembly of the double glazed window unit, the sealing member orstrip 45 is first mounted on the edges of panels 43 and 44 so that theedges of the panels are disposed in slots 5l and 52 of the strip. It isnot necessary that the edges of both panels set tight against the innersurfaces of web 41 as pointed out heretofore in connection with thesingle glazed window, nor that the panels be identical or precisely theAsame shape as the differences between the panels. Thereafter the stripsembracing the marginal edges of the panels are telescopically joinedwith the rails as more fully described above so that the strip isdisposed within the recess in the rail with flanges 56 and 51 on thestrip in engagement with the rounded top edges of side walls 36 and 31of the rail. When the panel and sealing strip are moved into therecesses in the rails, ribs 54 and 55 engage the side of the rails andbend or fold inwardly against legs 48 and 49 of the strip and thus offerlittle resistance to this movement. However, if a force is applied whichtends to separate the rails from the panels the ribs 54 and 55 will tendto unfold and expand outwardly against side walls 36 and 31 of the railand resist this movement. Thus, the panels 43 and 44 are securelysealed, spaced, resiliently supported and retained in the sash.

In order to afford and control communication with the space 53 betweenpanels 43 and 44, apertures 69 and 5l are drilled and tapped in theouter walls, such as 35 of the sash rails, and are adapted to receivesmooth-ended screws 82 and 63 Y which are aligned with apertures 64 and55 formed in the intermediate leg 5l) of the strip opposite theapertures 60 and 5l, respectively. Preferably the rounded ends of thescrews seat on and at the marginal edges of the apertures 54 and 55 andclose these apertures in the innermost position of the screws and openthese apertures when the screws are backed out and/or removed tures 60or 6| for the movement, treatment or change of the contents of the space53. If, for example, a dehumidied gas is to be admitted to the space 53,the source or" such gas is connected to the aperture opposite a vacuumpump means and the space 53 filled therewith as the original gas isremoved. After the operation is completed, the screws E2 and 53 arescrewed down tightly Y against the rubber strip thereby sealing theholes 64 and 65. Similarly dehumidifying agents may be injected into thespace 53 through either orv both apertures.

In order to adapt one sash or window frame so that it will accommodateeither single or double i glazing, the single glazing strip 3 and thedoubleV `glazing strip 45 of my invention may be formed with the samegross exterior dimensions so that either strip will nt tightly into thesame recess converted readily from single glazing construcl tion todouble glazing construction or vice versa by merely selecting a singleor double glazing i sealing strip for assembly in the sash. This featureof my invention permits conversion from single glazing construction todouble glazing sash or as each other; A the nature of the strip makingthe accommodations discussed above and also accommodating -9construction by mere replacement of the sealing strip withoutnecessitating replacement of -the sash. Since the cost of the sealingstrip is small compared to the cost of the sash, substantial savings'areeffected.

Figures 9 and 10 show particular modified forms of a single glazingstrip 'I0 and a double glazing strip 80 of like external conformationand size. In this case, strip '10 is substantially the same as strip 3described above except that legs and '|2 have greater effective widthand are, however, preferably undercut as indicated at 13 and 14,respectively, adjacent the web portion '15. The purpose of undercuttingthe legs is to eiect economy in fabrication of the strip by reducing theamount of rubber or other material used in the strip. The thickenedportions i@ and 11 of the legs serve to engage and tightly grip thepanel I disposed therebetween in the manner described above. Theintermediate leg 8| of strip 80 shown in Figure 10 is likewise undercutadjacent the web 84 as indicated at 82 and B3 while serrated thickenedportions 85 and 85 at the far end of leg 8| engage and grip the panels`43 and 44. Preferably the thicker far end of leg 8| has a longitudinalaperture 8T which with the serrations lends greater effective lateralresilient compressibility to accommodate variations in panel thicknessand maintain an eflicient grip and seal withall when the sash isassembled. In other respects, strips 'i0 and 80 function in the mannerdescribed above.

Whether in single or multi-glazed forrn the seal and bond establishedthrough the strip between the sash rails and the panel or panels of theglazing is such as to hold the several parts together in tight andsecure assembled relation. In fact the bond is such that for manypurposes no other means are necessary to secure the sash rails in thedesired relation to each other and to the glazing. For example, inwindows where the sash are pivotally supported in the middle of thebottom rail the mechanical bond afforded by the strip more than sufficesfor all manner of shipping, storing, handling and use of such rails. Onthe other hand where the sash are to be suspended from the top rail andparticularly where the glazing is large and heavy, I prefer to augmentthe strength of the sash by connecting the ends of the rails together asby the means suggested in Figures 11, l2 and 13 of the drawings. Thusthe ends of adjacent sash rail members are joined together in anoverlapping relationship to form a tight, strong, light proof joint. Asshown in Figures ll and 13, slots 93 and 9| are milled in top rail 3| toa. depth substantially the same as the depth of the recess in the sash.Alternate rails, the vertical rails 33 and 34 in this instance, whilehaving the same internal recess, size and shape as the top and bottomrails, are of lesser width by virtue of having thinner side Walls orlegs 39 and 43 which leave a snug sliding t in the slots S3 and 9|. Whenthe side rail 34 is joined to the tcp rail 3|, side walls 39 and 4B ofthe side rail (it into the slots 9) and 9| until the outer wall 38 ofthe side rails 34 abuts the end of the outer wall 35 of the top rail 3|as shown in Figure l2. The ends of the outer and side walls of the siderail lie hush with the exterior surface of the outer Wall 35 of the toprail as also shown in Figure 12. The slots 9b and 9| cut through theouter wall 35 of the top rail, Figures ll and '12, and cut away theinward parts of the ends of the side walls 3S and 31 of the top rail toa depth corresponding to the thickness of the legs 39 and 40 of the siderail so that the inner surfaces of the legs of the side rail and theinner surfaces of the legs of the top and bottom rails lie ush as at S2.Thus the recess 4| is common to all rails and identical throughout thewhole sash. A pin Se or other suitable fastening means may be insertedthrough aligned apertures drilled transversely through the ends of theside walls oi the side rail and the outer wall of the top rail, Figures11 and 12, to secure the rails together. The connection between railsends described with particular reference to Figure 6 also applies toyFigure l. K

I have mentioned my preference for using a single sealing 'strip to becarried around the whole periphery Vof the panel or glazing. In suchevent I prefer to cut V notches through the side walls ofthe strip asshown in Figure 15 to turn the cornersA of the strip around the cornersof the glazing as shown in Figure 16.

While I have illustrated and described preferred and certain .modifiedforms of my invention, changes, improvements and further modicationswill occur to those skilled in the art who come to understand theprinciples and advantages of my invention, and I do not care to belimited in the scope of my patent to the forms herein speciiicallyillustrated and described nor in any way inconsistent with the advance Ihave made over the prior art.
